STEPHEN STUCKY, OF LINCOLN, ALABAMA.

HYDRAULIC PROPULSION OF` SHIPS.

SPECIFICATION forming part of Letters Patent No. 243,656, dated June 28,1881.

Application filed May 23, 1881.

To all lwhom it may concern:

Be it known that I, STEPHEN, S'rUcKY, of Lincoln, in the county ofrIalladega, and in the State of Alabama, have invented certain new anduseful Improvementsin Hydraulic Propulsion of Ships. or Vessels; and Ido hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, making a part of thisspecification.

The nature of my invention consists in a novel method and means forpropelling vessels,as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings, in which-I Figure l is a plan view ofthe hull of a vessel embodying my invention.Fig. 2 is a partial side view, and Fig. 3 a rear view, of the same. Fig.4 is a detail view, and Fig. 5 section through x x.

My invention relates to that class of vessels which are propelled byejecting water from pipes arranged in the sides of the vessel; and itconsists in certain details of construction hereinafter more fully setforth.

1n Figs. l and 2 I have shown the hull A provided with numerous pipes, BB, ruiming from a certain point below the water-line on one side, underthe bottom, and up to a corresponding point on the opposite side. Thesepipes are arranged in groups of two or more, and between the groups aretriangular divisions O C, running the same as the pipes. The pipes B oneach side are further arranged in two divisions, those around the rearportion of the hull being used for propelling the vessel forward andthose in front of the middle being used for moving backward.

All the pipes are provided with narrow slots a a, as shown in Fig. 4,said slots being arranged in the propelling-pipes, so that water underpressure will pass out at different angles rearward, while the slots inthe backingpipes are arranged to emit the water at different anglesforward.

On each side of the vessel the two divisions of pipes are connected inthe following manner: Every alternate group is connected to one (Nomodel.)

supply-pipe, which receives water through a pipe, b, from vone end of aforce-pump, D, while the other alternate groups are connected to asimilarsupply-pipe,thatreceives waterthrough a pipe, b', from the otherend of the force pump. Suitable stop-cocks are, of course,provided tocause the water to be forced to either the propelling or backing pipes,as desired. When the pump is in operation it forces water at one strokethrough the slots in alternate groups of pipes, and at the return-strokethrough the slots in the other alternate groups of pipes, thusdischarging the water in in termittent jets.

The water may be supplied to the pump or pumps through pipes leadingfrom the bow of the vessel or in any other suitable or convenientmanner. y

The triangular divisions C protect the pipes from injury, and alsoreduce the friction ofthe hull in the water, because when' the vessel isin motion there is a vacuuln formed behind each division, the wateractually being in contact with the eXtreme angles of said divisions'only.

For atbottomed boats the pipes may be arranged torun horizontally, asshown in Fig. 3.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The combination,with the force-pump D, provided with the pipes b b atits opposite ends, of the pipes B, provided with the elongated slots a,one ofthe alternate groups of the pipes B being connected with the pipeb at one end of the pump-cylinder, and the other alternate group of thepipes B being connected with -the pipe b at the opposite end of thecylinder, substantially as described, and for the purpose set forth.

2. The hull A, provided with the triangular divisions C and pipes B,having slots a, in combination with the force-pump D and pipes b b',substantially as described, and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this26th day of April, 1880.
